- rick, such as that of an oil well, for supporting the tackle forboring orhoisting or lowering, and while primarily adapted for use inconjunction with the framework of a steel derrick, it will be obviousthat my improved coupling maybe employed for anypurposes wherein it isfound to be'applicable. 1

Important objects of the invention are to provide a substantial couplingunit for se-.

curing the adjacent ends of steel derrick frame-work members, which willfacilitate the erection and dismantling of such derrick structures, andwhich includes novel means 7 for maintaining the coupling in conditionfor convenient detachment.

Further objects of this invention are to provide a device of thecharacter described, in a manner as hereinafter set forth, which issimple in its construction and arrangement, strong, durable andefficient in itsuse, positive in its action, andcomparatively'inexpensive to manufacture.

To the accomplishment of theseand such other objects as may hereinafterappear, the

v invention consists of the-novel construction',

combination and arrangement of parts hereinafterspecifica'lly described,and illustrated in the accompanying drawing wherein is shown anembodiment of the invention, but it is to be understood that changes,vari ations," and modifications may be resorted to which come within thescope of the claims hereunto appended.

In the drawing forming a portion of this specification and wherein likenumerals of reference designate corresponding parts throughout theseveral views 5 j v Figure 1 is a perspective view of my improvedcoupling, illustrating the attachment of conjoining derrick structuremembers therewith.

T "Figure 6 is-a verticalsectional view of another modification of the coupling; lleferring indet'ail tothedrawing 1 denotes the body portion of the preferred form 01"" couplng which consists-ofan integral steel casting. The body;port i'on. '1-iscylindrical in contour andis fOrmedWith an upper bore 2-and a lower bore3. The bores 2 and 3 are separated from each other by'the centrallydisposed seat m'e nber fl which extends around the'periphery of the boreintermediate ofboresQ-and 3i The marginal edges of the upper aha" lower"faces of the {seat member 4,-adjoining the peripheries ofresp'ectiveboresQ and 8, are formed to provide recessed air cular finished seats'5and 6, respectively.

The seats 5 and "6 are adapted for the reception ofthe adjacent ends.ofjthe r'espec-' tive leg members7 and 8, which 'latterconstituteaportion of the framework of the derrick structure and are made fromtubing or pipe permitting oftheir engagement in the recessed seats?) and6." I

The faces'of the upper and lower bores 2 and 3 are eachprovi'ded'with a'plurality of vertically extending ribs; 9 having lfinished faces adaptedto frictionally engage the outer face of the leg members 7, 8,when thelatter are mounted inposition-in respective bores 2 and'3and seats 5and-6. Each of the ribs 9 increases in width from its iiiner to itsouter end. i f It will herebe noted that the construction of the bodyportion- 1' providing; the machined rib faces andcseats 5'and 6,willzestablish an accurate, substantial,and rigid union between conjoinin'gleg members 7 e and 8, The provision ofithe ribs 9 will not only providefor the economicmanufacture ofthe couplingi'but will also facilitateitheassembly -or detachment of the associated members 7 and 8 by reducingtheir frictional engagement, inrespective bores 2. and 3, to' a" nnmmum.Further the periphery ofv the bores 2 and 3 between adjacentverticaliribs V 9 provide clearances-1O wh ichare utilized for storing acheap heavy lubricant to prevent corrosion of the-connections and tofurther facilitate the erection or dismantling of the derrick structure.The varying width of the ribs 9 will serve to confine the lubricant inthe clearances 10.

Formed integral with the periphery of the body portion 1 is a pair oflongitudi: nally extending and laterally disposed flanges 11, 12, one ofsaid flanges being positioned at right angles relatively to the other.Each of the flanges 11, 1.2, is provided with three aligned apertures13, 14-, and 15, respectively. The center apertures 1 of the flanges 11,12, are utilized for securing the horizontal girts 16 to respectiveflanges 11 12, and the end apertures 13 and.15 are utilized for securingthe diagonally disposed brace members 17 to respective flanges 11 and12. The flange apertures 13, 14 and 15 are elongated for the receptionof bolts 18, commonly known to the trade as track bolts having shouldersconforming to the contour of the elongated flange apertures 13, 14 and15. Each of the bolts 18 is provided with securing nut 19 of the usualconstruction and the adjustment or removal of the latter is facilitatedas the engageinent of the bolts 18 in elongated flange apertures 13, 14cand 15 is fixed to prevent its rotation. Such construction is essentialas the rig builder is usually employed in hazardous positions on derrickconstruction, supporting himself with the aid of one hand whileadjusting the nut 19 upon the bolts 18 with the other.

Themodificationillustrated in Figure 4:

of the drawing shows a coupling comprising a body portion 20 including acomplemental section 21, and constructed from steel plate instead of acasting as in the preferred form. -The body portion 20 is formed toprovide lateral flanges 22, one of which is disposed at right anglesrelatively to the other. i The complemental section 21 is formed with apair of narrow longitudinal flanges 23, each of which is secured to itsrespective body portion'flange 22 by means of the rivets 2 The bodyporttion 20 and its complemental section'21 forma bore 25 having acentrally disposed annular groove 26 preferably pressed outwardly on theperiphery of the bore 25. A seat member 27 is mounted in the annulargroove 26 and secured therein by the asse'mbly of the section 21 withthe body portion 20, as above described.

The seat member 27 is formed to provide an annular seat 28 on the upperface thereof and an annular seat 29 on its lower face. The seats 28 and29 are provided for the reception of adjacent leg members as de scribedrelatively to the preferred form.

The modification shown inFigure 6 pro vides a coupling identical inconstruction grooves 26.

lit will be noted that the two modifications of the coupling providestructure functioning identically to that disclosed in my preferred formwith the exception thit the bores thereof are not ribbed or him chinedand in consequence would not pro vice as accurate a union as when usingthe preferred form of coupling.
